Suicide runs in families. So you are high risk. You need to take this seriously. Your goal is to reach that point when you do not base your decisions on whether to live on the concern for the bf's possibly being devastated.

You need to figure out why you do not like school. If you are depressed, then you need treatment. If you do not like the subject matter for real (and not just because you currently are not interested in any activity as a symptom of your depression), then you need a new major. Learning something you do not enjoy and then having to work in the field you do not like just to pay off your FAFSA loans would be a very grim future for you. Please start by following Piraeus's recommendations, and then get together with whoever is responsible for guiding students in major selection at your college. You need to take the issue seriously. You basically used the boyfriend for comfort and support, and you have lost that crutch. A person who has lost her crutch can easily fall and hurt herself pretty badly. Be very careful. As Piraeus said, we will be here for you and hope to get positive updates from you, eventually.
